What this dot point is asking
CCEA wants you to understand safe working in the workshop: the difference between a hazard and a risk, the idea of a risk assessment, the use of personal protective equipment (PPE), safe use of tools and machines, and safe handling of materials and substances. Safety appears in both the written papers and the practical project.
The answer
Hazard versus risk
These two terms are often confused, so the distinction is examinable.
For example, a circular saw is a hazard; the risk of injury is high if it is used without a guard and with loose clothing, but low if the guard is fitted, the work is clamped and the operator is trained.
Risk assessment
The aim is to remove or reduce risks before work starts, not to react after an accident.
Personal protective equipment
Safe use of tools and machines
A blunt tool is more dangerous than a sharp one because it needs more force and can slip, which is a common exam point.
Safe handling of materials and substances
Worked example: assessing a workshop task
Examples in context
- Example 1. Spray painting
- Solvent fumes are the hazard; the risk is reduced by a spray booth, ventilation and a respirator, showing controls plus PPE.
- Example 2. Using a lathe
- The rotating chuck and swarf are hazards; goggles, tied-back hair, a guard and a clamped tool reduce the risk to an acceptable level.
- Example 3. A school project
- Before any practical work a pupil notes the hazards of each process (drill, saw, glue) and the controls, which is a simple risk assessment that examiners expect to see in the Unit 3 project.
Being able to separate hazard from risk and describe sensible controls and PPE lets you answer both the "explain the difference" and "describe the precautions" questions.
Try this
Q1. Define the term hazard. [1 mark]
- Cue. Anything that could cause harm (a machine, sharp tool, dust or chemical).
Q2. What are the main steps of a risk assessment? [2 marks]
- Cue. Identify the hazards, judge the risk and who could be harmed, then decide controls to reduce the risk (and review).
Q3. Name two items of personal protective equipment used in the workshop. [2 marks]
- Cue. Any two of: safety goggles, apron/overall, dust mask/respirator, ear defenders, gloves.
Q4. Why should a workpiece be clamped rather than held by hand when drilling? [2 marks]
- Cue. So it cannot spin or be pulled by the drill, which prevents injury and keeps the hole accurate.
Q5. Give one reason a blunt tool can be more dangerous than a sharp one. [1 mark]
- Cue. It needs more force and is more likely to slip, causing an accident.

CCEA style4 marksExplain the difference between a hazard and a risk, using a workshop example.Show worked answer →
A hazard is something that could cause harm (1), for example a rotating drill bit or a sharp chisel (1).
A risk is the chance that the hazard actually causes harm, and how serious it would be (1). For example, the risk of the drill catching loose hair is high if hair is untied but low if it is tied back and a guard is used (1).
CCEA style4 marksDescribe two safety precautions a pupil should take when using a pillar drill.Show worked answer →
Wear safety goggles to protect the eyes from flying chips, and tie back long hair and remove loose clothing or ties so they cannot catch in the rotating chuck (1, 1).
Clamp the workpiece securely (for example in a machine vice) rather than holding it by hand so it cannot spin, and use the guard, keeping fingers clear of the bit (1, 1).
